Abstract

Two experiments were performed to study lexical decision time to word and non-word Hebrew trigrams as a function of stimulus probability, visual hemifield and responding hand. The results indicate that lexical decision time to words is shorter than to non-words. In addition, although decision time to words is significantly shorter with right hemifield stimulation than with left hemifield stimulation, decision time to non-words is the same whether they are presented to the right or left hemifield. Decision time to non-words decreases almost linearly as stimulus probability increases from 0.25 to 0.75, whereas decision time to words decreases in a concave manner apparently approaching an asymptote at a stimulus probability of 0.75. Responding hand is not significant as a main effect or in any interaction with any other variable. The data are discussed in terms of several models of hemispheric linguistic superiority.

摘要

进行了两项实验，以研究希伯来语三字词和非字词的词汇判断时间，该时间是刺激概率、视觉半视野和反应手的函数。结果表明，对字词的词汇判断时间比对非字词的要短。此外，尽管右半视野刺激下对字词的判断时间明显短于左半视野刺激下的，但对非字词的判断时间在呈现于右半视野还是左半视野时是相同的。随着刺激概率从0.25增加到0.75，对非字词的判断时间几乎呈线性下降，而对字词的判断时间以凹形方式下降，在刺激概率为0.75时显然接近渐近线。反应手作为主效应或与任何其他变量的任何交互作用均不显著。根据几种半球语言优势模型对数据进行了讨论。
